Abstract

Lors de la formation d'une première configuration de distribution de lumière, le circuit de commande est configuré pour commander les grandeurs des courants de commande du premier élément d'émission de lumière et du deuxième élément d'émission de lumière. Lors de la formation d'une deuxième configuration de distribution de lumière, le circuit de commande est configuré pour commander de telle sorte que la grandeur du courant de commande du deuxième élément d'émission de lumière est plus petite que lors de la formation de la première configuration de distribution de lumière et/ou de telle sorte que la durée pendant laquelle le courant de commande doit être délivré au deuxième élément d'émission de lumière est plus courte que lors de la formation de la première configuration de distribution de lumière.When forming a first light distribution pattern, the control circuit is configured to control the magnitudes of the drive currents of the first light-emitting element and the second light-emitting element. When forming a second light distribution pattern, the control circuit is configured to control such that the magnitude of the driving current of the second light-emitting element is smaller than when forming the first light distribution pattern and/or such that the time for which the drive current is to be supplied to the second light emitting element is shorter than when forming the first light distribution pattern.
